A powerful IT support is becoming essential even with other aspects of power generation, including climate and environmental questions and international power generation system coordination.The Romanian power sector is prone to using sophisticated computer systems with advanced IT programs and applications as a standard, varying from basic administrative systems to production control and customer billing systems. After the deregulation of the energy sector in 1998, a whole new market opened for applications within electricity trade, customer service and measurement analysis. The current trend and also the biggest challenge is for the power companies to integrate the existing function-specific applications on separate servers into fewer and larger compatible systems. The fast development and severe competition have moved corporate IT issues gradually from the system manager level to the CEO level and turned them into major strategic decisions worth the investing of both monetary resources and manpower.
